For Ascot she changed into a canary-yellow coat, worn over a patterned dress, a co-matching hat and white gloves.

The Queen was joined in the royal horse-drawn carriage by Charles' wife Camilla, the Duchess of Cornwall, who was dressed in an elegant powder blue outfit.

Her Majesty was also joined by Prince Charles, who looked dapper in a black top hat and grey tails, and Princess Anne, who looked chic in a blue and white checked jacket and navy skirt.

The Queen was free to enjoy her day at the races after ploughing through Theresa May's nine-minute speech, which was dominated by Brexit-related bills.

The terror atrocities in Manchester and London, plus the tragic fire at Grenfell Tower, were also part of the speech as the Queen read out promises for tougher measures to tackle terrorism and a public inquiry into the inferno.

Of course there were some who went the extra mile, such as one lady who matched her bright pink hat to her nails, which were two-toned with purple tips.

Well, it is pretty hot out there today - so what better way to shield yourself from the sun?

Poldark actress Eleanor Tomlinson and Olympic swimmer Ellie Simmonds were also in attendance.

As the mercury creeps up thanks to the on-going heatwave in the UK, visitors to the annual event seemingly looked for ways to stay in the shade.

The five-day event, which takes places in Berkshire, will host 300,000 revellers, 30 races and dish out more than £6.5million in prize money in total.

High-spirited racegoers made their way into the grounds earlier today, and basked in the balmy temperatures.

However, those attending needn’t worry too much about the heat getting the better of them – as organisers are reportedly willing to relax their formal dress code to combat the effects of the summer heatwave.

The Times said that men will be allowed to remove their jackets if they get too hot – even though top hat and tails are usually compulsory in the Royal Enclosure.

Meanwhile, for the first time, women will be able to wear jumpsuits in the Royal Enclosure as organisers give a nod to their “awareness of seasonal trends” – but they must be full-length.

For female racegoers, strapless, off the shoulder, halter-neck, spaghetti straps and dresses with a strap narrower than 1in (2.5cm) are still banned in the exclusive area.

Midriffs must be covered and fascinators are also forbidden.
